Description

a chest press

technical field

The utility model relates to the technical field of medical machinery, in particular to an external chest presser.

Background technique

Cardiac resuscitation usually requires the operator to be accurate, skilled, and in place. And pay attention to pressing the correct part, the accuracy of the operation method. There are different requirements for the compression frequency and subsidence depth for patients of different ages, and the compression should be stable, even and regular. The pressing part should not be too low, so as not to damage the liver, stomach and other internal organs. The pressure should be appropriate, too light is not enough to promote blood circulation; too heavy will cause fracture of the sternum, resulting in pneumothorax, especially for children, it is easy to press too much or too lightly, which affects the rescue. Most of the existing cardiac pressers do not have a compression depth limiting device, nor do they have a corresponding adjustment function to adjust the limit compression depth. It still depends on the experience of the medical staff, and sometimes the sternum fracture of the rescued is unavoidable.

There are some existing pressing devices with complex mechanisms and multi-purpose motors or cylinders and sensors to achieve pressing. However, due to the complex devices, they are inconvenient to carry and inconvenient to use in emergency situations.

Utility model content

In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a chest presser, which effectively solves the problem that the patient's long-term posture during operation consumes too much physical strength, thereby affecting the operation effect.

Its technical solution is to include a horizontal flat plate, vertical support rods on the lower sides of both ends of the flat plate, a cylinder vertically penetrating the flat plate on the flat plate, a vertical screw rod in the cylinder, and the screw rod and the cylinder are connected. The upper end of the cylinder is provided with an annular protrusion, the lower end of the screw rod extends out of the cylinder and is placed under the cylinder, and the lower end of the screw rod is fixed with a horizontal pressing block.

The utility model has an ingenious structure, and can adjust the depth of compression depression according to different patients, which can well serve the requirements of patients of different age groups, can perform compression for a long time, reduce human errors, ensure compression strength, and reduce chest compression. Complications, improve cardiac resuscitation effect and success rate, simple and practical, easy to implement, wide adaptability.

Detailed ways

The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

1 to 3, the utility model includes a horizontal flat plate 1, with vertical support rods 2 on the lower sides of both ends of the flat plate 1, and a cylinder 3 vertically extending through the flat plate 1 on the flat plate 1. The cylinder 3 There is a vertical screw 4 inside, the screw 4 and the cylinder 3 are connected by thread, the upper end of the cylinder 3 is provided with an annular protrusion 5, the lower end of the screw 4 extends out of the cylinder 3 and is placed under the cylinder 3, and the lower end of the screw 4 is fixed There is a horizontal pressure block 6 .

In order to facilitate pressing, the upper end of the screw 4 extends out of the cylinder 3 and is placed above the cylinder 3 , and the upper end of the screw 4 is provided with a horizontal pressing plate 7 .

In order to avoid pressure sores or pressure injuries, arc transitions are formed around the lower end of the pressure block 6 .

There is no separation between the cylinder 3 and the flat plate 1 .

The cylinder 3 has a scale marking the distance.

A compression spring is connected between the pressing block 6 and the flat plate 1 .

When using, the patient is lying flat, the flat plate 1 is placed above the patient and the surrounding support rods 2 are firmly supported, and then the pressure block 6 is placed in a suitable position in front of the patient's chest, and the pressure block 6 is held against the patient. At this time, hold the pressure plate with one hand. 7. Screw the cylinder 3 with the other hand to adjust the distance between the upper end of the cylinder 3 and the plate 1. The distance between the cylinder 3 and the plate 1 is the maximum sternum subsidence. Release both hands and place them on the pressure plate. 7, and press down, when the annular protrusion 5 on the upper end of the cylinder 3 is in contact with the flat plate 1, it suddenly relaxes, pay attention to the frequency of pressing and the smoothness of the airway.

When the utility model is in use, by adjusting the distance between the annular protrusion 5 on the upper end of the cylinder 3 and the flat plate 1, the range of the pressing depression can be adjusted, especially for infants and young children, it can effectively avoid the pressing depth from being too large, and can also make medical care The personnel can press with confidence and boldness, so as not to miss the rescue time if the force is too light.

The utility model has an ingenious structure, and can adjust the depth of compression depression according to different patients, which can well serve the requirements of patients of different age groups, can perform compression for a long time, reduce human errors, ensure compression strength, and reduce chest compression. Complications occur, it is easy to carry, can be used directly at the rescue site, and improves the resuscitation effect and success rate of the heart. It is simple and practical, easy to implement, and has wide adaptability.
